Answers
1
Which sub-atomic particle has a positive charge?
Electrons
Protons
All of them
Neutrons
2
Why are group 0 called group 0?
They didn't exist for ages so we had zero knowledge on them
Mr Zero discovered them
They need 0 more electrons to be full and stable
They have 0 electrons in the outer shell
3
Why does the reactivity increase as you go down group 1?
Because you need less energy to react them
Because you need more energy to react them
Because it is easier for the outer electron to be gained
Because it is easier for the outer electron to be lost
4
How many protons does Sodium (Na) have?
11
34
12
23
5
Why are group 0 said to be inert (unreactive)?
They all have 2 electrons in the outer shell
They have full outer shells
They are lazy
They have eaten too much and are full
6
Why does the boiling point change as you go down group 0?
Less weak intermolecular forces, less energy is needed
